Systems and methods for broadcasting an audio or visual alert that includes a description of features of an ambient object extracted from an image captured by a camera of a doorbell device are provided. Such systems and methods can include the camera capturing the image when the ambient object is within a field of view of the camera and a processor receiving the image from the camera, processing the image with an artificial intelligence model to identify and extract details of the features of the ambient object, and initiating a broadcast of the audio or visual alert by an alert device associated with the camera, wherein the audio or visual alert can include the description of the features of the ambient object.

A first device is detected within a geofenced area of an establishment. A second device is determined to be within the geofenced area. A first individual associated with the first device is instructed to enter the establishment and complete a first portion of opening security procedures associated with an opening of the establishment. Upon completion of the first portion, a second individual associated with the second device is instructed to enter the establishment for a second portion of the opening security procedures. The first individual and the second individual are monitored through video feeds during the first portion and the second portion of the opening security procedures for compliance with the opening security procedures.

This application discloses a video pre-recording method and video camera, and an electronic device. The video pre-recording method includes: adding a pre-alarm area on a periphery of an alarm area; when occurrence of a predefined event in the pre-alarm area is detected, switching the video camera from a standby state to an operation state, and starting recording to obtain a first video; maintaining the video camera in the operation state, and detecting whether a predefined event occurs in the alarm area; and if occurrence of the predefined event in the alarm area is detected, taking a preset duration of the first video as a pre-recorded video of a second video, where the second video has a starting time that is the same as a time when the predefined event occurs in the alarm area. Based on this, this application can enable low-power video cameras to perform a video pre-recording function.

Some embodiments provide a method for separating the motion detection zone(s) of an A/V recording and communication device from the motion alert zone(s) of the A/V recording and communication device. For example, an A/V recording and communication device may be configured to generate motion alerts, and to record audio and video footage, when an event is detected within a selected motion alert zone (e.g., within a defined radius around the A/V recording and communication device). However, the A/V recording and communication device may not generate a motion alert for an event detected outside of the selected motion alert zone, even though the device may still record audio and video footage for the detected event (e.g., when the event is within a selected motion detection zone).

A surveillance camera system includes a camera that acquires images and that has an adjustable field of view. A processing device is operably coupled to the camera. The processing device allows a user to define a virtual mask within the acquired images. The processing device also tracks a moving object of interest in the acquired images with a reduced level of regard for areas of the acquired images that are within the virtual mask.

Disclosed is a video patrol method and apparatus. The number of alarm messages for each capture device is stored in a database. According to the number of alarm messages for each capture device, the weight corresponding to each capture device is determined. The greater the number of alarm messages for a capture device is, the greater the weight corresponding to the capture device is. The play duration corresponding to each capture device is determined according to the weights. The greater the weight corresponding to a capture device is, the longer the duration for the capture device is. The play time period for each capture device is determined according to the determined play durations. The management device controls the video wall to perform video patrol according to the determined play time period for each capture device.

The conventional image surveillance technologies relevant to the present invention had the potential of failing in detect ion due to the intrusion duration time being set too long and thereby allowing an intruder to pass a warning line before the preset intrusion duration had elapsed. The intrusion detection device according to the present invention is provided with: a detect ion means that detects, in an image, an intrusion position in a specific region by an object that has intruded into the specific region; and a control means that associates the intrusion position with a prescribed time period, wherein the detection means outputs an alert when the object, in the image, has stayed in the specific region for the prescribed time period or longer.

A method for security and/or automation systems is described. In one embodiment, the method includes identifying image data from a signal, analyzing the image data based at least in part on a first parameter, identifying a presence of an object based at least in part on the analyzing, and detecting an object event based at least in part on the identifying.

A monitoring information recording apparatus according to one aspect, includes a recording processing unit configured to record, in a case that monitoring information including-at least one of a captured image of a monitoring target and a measurement value calculated based on the captured image meets a predetermined criterion, the monitoring information in a first mode. The recording processing unit, records, in a case that the monitoring information has not been recorded in the first mode for a predetermined period of time or longer, the monitoring information in the first mode regardless of whether the above criterion is met or not.
